Your Child's Confirmation Book

Indeed, the chapter on the Trinity is the best. Fr Sheed puts it beautifully:

Now it is true that the doctrine of the Blessed Trinity is a mystery, and that we can know
it only by faith.
But what we have just been hearing is not the mystery of the Trinity,
it is not the mystery of anything, it is wretched nonsense.
It may be heroic faith to believe it, like the man who
Wished there were four of 'em
That he might believe more of 'em;
or it may be total intellectual unconcern?
God has revealed certain things about Himself,
we accept the fact that He has done so,
but find in ourselves no particular inclination to follow it up.
God has told us that He is three persons in one Divine nature, and we say "quite so,"
and proceed to think of other matters?


For the doctrine of the Trinity is the inner, the innermost, life of God, His profoundest
secret.
He did not have to reveal it to us.
We could have been saved without knowing that ultimate truth.
In the strictest sense it is His business, not ours.
He revealed it to us because He loves men and so wants not only to be served by them,
but truly known by them.
It is the surest mark of love to want to be known.
The revelation of the Trinity was in one sense a more certain proof even than Calvary that
God loves men.
To accept it politely and think no more of it is an insensitiveness beyond comprehension
in men who quite certainly love God:
as many certainly do who could give no better statement of the doctrine than the believer
in the model dialogue we have just been considering.
How did we reach this curious travesty of the supreme truth about God?
The short statement of the doctrine is, as we have all heard all our lives, that
there are three PERSONS in one NATURE.
But if we attach no meaning to the word PERSON,
and no meaning to the word NATURE,
then both the nouns have dropped out of our definition,
and we are left only with the numbers three and one,
and get along as best we can with these.
